砂性土地基深基坑工程对周边环境的影响分析
Effect of sandy soil deep excavation engineering on adjacent circumstance
摘要
Abstract
With the rapid development of modern cities, the number of deep excavation sites adjacent to complicated surroundings is increasing significantly. The construction of excavations will change the soil stress around the site and affect the surrounding circumstance. According to the practice of a sandy deep foundation site neighboring the metro tunnel in Hangzhou, the retaining structure of deep foundation and the deformation of tunnel nearby during the construction of excavation are simulated by Plaxis considering the attenuation law of the deformation of the soils around the foundation. By analyzing the measured data, the results show that the calculated results are is basically consistent with the field surveys. Furthermore, the retaining structure, surrounding sandy soils and the adjacent tunnel will shift toward the site during the construction of deep excavation. The deformation rules greatly related with the construction schedule of excavation and the distance of site. This study may provide reference for the design of sandy deep foundation pit engineering.关键词
